VENTILATOR -FOR CARS.

Specicaton of Letters Patent.

Patented. Aug. 1, 1905.

Application led July 2, 1904. Serial No. 215,128.

To all whom/ it may concern:

Beitknown that I, HENRY KENNELL, a citi-v zen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York,have invented a new and Improved Ventilator for Cars, of which the following is a full, clear, and exact description. The purpose of the invention is to provide means for Ventilating cars or other vehicles by introducing a thorough circulation of air through the clearstory of the car, thus pretion, thus creating a suction'to draw the foulI -air out from the body of the car. y

Another purpose of the invention isto provide a means whereb'y when a `ventilator is closed operating mediums, which are in the nature of wings acted upon by the currents of air induced by the movement of the vehicle, will at such time move to such a position as to offer the least possible resistance to the air as the vehicle moves forward.

The invention consists in the novel construction Aand combination of the several parts, as will be hereinafterfully set forth, an pointedout in the claims.

Reference is to be had to the accompanying drawings, forming a pa-rt of this specification,

in whichsimilar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a part of the upper or roof portion of a car, including the clearstory and illustrating a ventilator in an open position at the rear portion of the clearstory, the roof of the clearstory being shown in section and the part of the clearstory cut away being indicated by dotted lines. Fig. 2 is an enlarged longitudinal Vertical section through that portion of the car shown in Fig. 1, showing the ventilator open in Apositive lines and closed in dotted lines. Fig. Sis an enlarged vertical section taken practically on theline 3 3 of Fig. 4, representing the ventilator at the rear end of the clearstory open in positive lines and in dotted linesv showing the position of the said ventilator when closed.' Fig. 4 is a section taken practically on th v line 4 4V of Fig. 3; and Fig. 5 is a vertical longitudinal section Vof an en d portion of the roof of a regular vrailway-car, illustrating the v adaptation of the improvement thereto.

A represents the roof of a car, and B the clearstory which is erected on the roof, which clearstory is provided at each end with a transverse opening 10. This opening is preferably provided at its upper portion with a longitu dinal metal strip l1 flush with the outer side face of the walls of the clearstory in which the said openings 1() are made. At each end.

of each opening 10 in the said clearstory a,

bearing 12 is formed of any approved construction, and in the bearings 12 at each end of the clearstory a shaft 13 is mounted to loosely turn, which shaft extends out beyond the side faces of the clearstory, as is shown in Fig. 1.

A ventilator C is secured, preferably, to the front or outer side of each shaft 13, and each ventilator C in one position is adapted to close the opening 10 adjacent to which it is located and in another position uncovers the said open'e ing to a greater or lesser extent. Eachventilator C, as is shown particularly in Fig. 2,

comprises an outer member c and inner mernber c' and a socket member c2, to which the said shaft 13 is secured, and when a ventilator C closes the opening 10 at the end of the clearstory the outer/ member c of the ventilator assumes a vertical position in engagement with the end walls of the opening 10, while the in'- ner member c engages with the inner face of the strip 1l4 at the upper edge of the opening 10; but the said parts c and c of the ventila tor may be so disposed that when the outer or lowermember-c is in closing position the upper or inner member c will engage with the inner wall of the 'said opening 10 at the upper edge of the same.

The ventilators C are operated by the action of the air on-wings D. rl`hese wings D are located at the outer ends of the shafts 13 and are connected with the inner'sides of the Vsaid shafts. To that end bearings 16 are prolent to about one-half of the circumference of the shaft, and these grooves 111, as is shown in Figs. 3 and 4, are provided at their ends with cushions 15, usually of an elastic material, the end portions of the grooves being longitudinally recessed to receive the said cushions. .Inl each Zbearing 15 a set-screw 17 is located, and'mthe said set-screws extend down into the grooves 14, being adapted for engagement in one position of the wings D with one or the other of the cushions 15. As the wings D are connected with one side of the shaft 13 and the ventilators C with the opposite side of the said shaft, the wings and ventilators are in parallelism. It will be understood that the wings and the ventilators may be so attached to the shafts y13I that their ends will be in longitudinal alinement.`

In the o-peration'o'f the ventilators when a car is in motionv the forward ventilator will be closed, and the action of the wind on the wings of that ventilatoreshaft will carry the said wings to such an angle rearwardly as to prevent the wings offering any resistance to the air while the car is in motion. On the other hand, the action of the air on the wings D at the rear of the car will cause the said Wings to be carried upward and outward unyl til the set-screws 17 in thel bearings on the 1 rear wings D engage with the upper cushions 15, (shown in Fig. 3,) thus causing the ventilator C at the rear to assume a correspond-- lng angular position to the rear wings and uncover the rear opening 10 in the clearstory to a greater or lesser extent. As the door of the car,` is opened or while the car is in transit the air entering the car will drive out the foul air atthe opening 10 at the rear of the clearstory .of the car, assisted by the suction naturallycreated at the said rear opening 10 by the movement of the car through the atmosphere, and under such conditions it is obvious that the foul air in the car is constantly drawn out therefrom and fresh air is supplied without subjecting the passengers of the carto unpleasant drafts.

In Fig. 5 I have illustrated an adaptation of the ventilator to a railroad-car, which is usually provided with an extended hood A at the ends @of the elearstory B, and in order that the openfffing 10, which is made in the clearstory and "1 kis opened and closed by the ventilator C', may

not receive cinders and loosely-iiying particles a screen 18 is carried from the ends of the car to thesides and ends of the hood A', thus covering the said hood in such manner as to prevent the entrance of cinders and yet not interfere with the passage of air. In the adaptation of the Ventilating device to a railroad car the ventilator C when closed is made to engage at its longitudinal edges with stops 19, of any approved construction, and a regulating-rod 20is employed for each of the ventilators C of a car, and by the movement of the said regulating-rod upward or downward the ventilators C may be opened more or less, as occasion may demand.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-4 1. In cars and like vehicles, aelearstory having an opening at each end, a ventilator mounted on a shaft at each opening, and wings haring limited turning movement on the shafts for operating the said ventilators.

2. In a car or similar vehicle, a clearstory having an opening at each end, a ventilator for each opening, adapted to open and close the same, a shaft on which the ventilator is secured, and wings at the outer ends of the shafts, having limited movement on the shaft and serving in one position to operate the ventilators to move them to an open position.

3. In a ear or similar vehicle, a clearstory having an opening at each end, a shaft jonrnaled at each of the said openings, a ventilator secured to the said shaft, adapted to cover or uncover the openings in the ends of the clearstory, the said ventilator being provided with an inner and an outer member, wings located at the ends ofthe shafts, bearings for the shafts carried by the said wings, the said shaft within the said bearings being provided with circumferential grooves, and set-screws extending through the bearings into the said grooves of the shafts, for the purpose described.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.

HENRY KENN ELL.
